That refers to marriage, not abortion. You are taking it completely out of context.
Homosexuals are not bearing false witness unless they try to hide who they really are. There is no dishonor to parents to have a homosexual child. Allowing homosexuals to marry the person they love means that they won't be committing adultery. Lastly your insinuation about homosexuals being predatory pedophiles only exposes your own ignorance.
Do not "murder". That is the whole thing about abortion. The rest, maybe you are not seeing enough into it.
Active homosexuals do bear false witness (according to convenience). Any time they want to walk among straight people, they "pretend" to be straight, for employment, to get things, etc. If they are trying to "seduce" a future partner or want to swing a person to their way of thinking, they use deception (false witness).
How many parents lead their children into a group of adults and declare "this child will be a homosexual when they grow up, and I will be so proud"? How many parents say I know this child will be the "result" of the love you share to homosexual children?
Active homosexuals do not "honor" their parents. They cannot give them grandchildren biologically (and while I understand that not all children have children, most straight marriages DO have children), so the parent is stressed, wondering if this will be the day the child from outside sources is taken out of their lives. Most parents have been taught in this society to "accept" whatever a child does, and most will say they are proud of their children, no matter WHAT they do, but that does not make them honored. Parents that meet together offer condolences and pity for other parents that have homosexual children (something the active homosexuals are oblivious to, or ignore); they are not requesting helpful tips for raising a similar homosexual child....
As far as "coveting": a child can be any age. I used it to avoid printing son or daughter, since "child" can be either. I did not bring pedophilia into the discussion, you did. When an active homosexual seduces a child (grown or otherwise), they are taking a person from another's family, and contributing to the dishonoring of the other's parents.
You asked where the LORD said it, and it was shown to you. Instead of looking at the facts, you want to pretend it doesn't apply. Sad, many people today do that, they are perfectly aware of their rejection of the LORD and HIS WORD, yet they pretend that they love HIM, and follow HIM.
